However, it would be appreciated by those skilled in the artthat other processes and/or materials may be also applied.

Referring to FIG. 1 and FIG. 2, an input assembly 100 according toembodiments of the present disclosure includes a touch panel 10, adecoration enclosure 20 and a fingerprint identification structuredecorated by the decoration enclosure 20. In the illustrated embodiment,the fingerprint identification structure can be a fingerprint chippackage structure 30 or other component with a function of fingerprintidentification.

The input assembly 100 according to embodiments of the presentdisclosure can be applied to a terminal 1000, and the terminal 1000 canbe configured as an electronic device such as a mobile phone or atablet. It can be understood that, the terminal 1000 includes but is notlimited to examples in the present embodiment. In some embodiments, theterminal 1000 further includes a screen 80 configured to display contentand a flexible screen circuit board 50 coupled to the screen 80.

In some embodiments, the touch panel 10 is located above the screen 80,and includes an upper surface 12 and a lower surface 14, as shown inFIG. 2. The upper surface 12 is opposite to the lower surface 14. It canbe understood that, the upper surface 12 of the touch panel 10 is afacade of the input assembly 100, facing to a user. The user can makegesture operations (for example clicking or sliding) on the uppersurface 12, so as to control the terminal 1000 to achieve correspondingfunctions.

The touch panel 10 can be made of light-transparent materials, such asglasses, ceramics or sapphires. As the touch panel 10 is configured asan input part of the terminal 1000, the touch panel 10 always sufferscontacts, such as impacts or scratches. For example, when the user putsthe terminal 1000 into his/her pocket, the touch panel 10 can bescratched and damaged by keys in the pocket of the user.

Therefore, the touch panel 10 can be made of materials having highhardness, for example the above-mentioned sapphires. Certainly, aprotecting cover plate can be attached on the upper surface 12 of thetouch panel 10, so as to prevent the touch panel 10 from beingscratched.

Furthermore, the touch panel 10 includes a display region 15 intendedfor the user to view the content displayed in the screen 80 and anon-display region 16 for receiving the fingerprint identificationstructure. In general, a middle region of the touch panel 10 isconfigured as the display region 15, and the non-display region 16 isarranged at a periphery of the display region 15. For example, thenon-display region 16 is located at a top side or a bottom side of thedisplay region 15.

As the touch panel 10 is made of the light-transparent materials, thus,the user can view content displayed in the screen 80 of the terminal1000 through the display region 15.

For allowing the terminal 1000 to have a better appearance, ink can besprayed on a lower surface 14 of the non-display region 16. The ink canhave a color such as white, black or blue, and so on. A specific colorcan be set according to actual requirements. The ink can not onlysatisfy requirements of the user for terminals 1000 having variouscolors, but also shield structures inside the terminal 1000 so as toreach an effect of beautifying the terminal 1000.

In some embodiments, a shape of the touch panel 10 can be designedspecifically according to a shape of the terminal 1000, for examplebeing configured as a rounded rectangle.

Furthermore, the touch panel 10 has a mounting hole 17. In the presentembodiment, the mounting hole 17 is configured as a through hole runningthrough the upper surface 12 and the lower surface 14. In otherembodiments, the mounting hole 17 can be configured a blind hole formedin the lower surface 14.

In the present embodiment, the mounting hole 17 is configured to have along circle shape. Certainly, in other embodiments, the mounting hole 17can have various shapes according to specific requirements, for examplea round or oval shape. Therefore, examples of the shape of the mountinghole 17 in the present embodiment cannot be construed to limit thepresent disclosure.

In some embodiments, the decoration enclosure 20 is fitted in themounting hole 17 and fixedly coupled to the touch panel 10. Thefingerprint chip package structure 30 is accommodated in the decorationenclosure 20 and fixedly coupled to the decoration enclosure 20.

In general, a receiver of the terminal 1000 is disposed in a top regionof the terminal 1000. Therefore, for preventing the mounting hole 17from having an interference with the receiver, in some embodiments, themounting hole 17 is provided in a bottom region of the touch panel 10,thereby providing a relatively large design space for the mounting hole17. Furthermore, the mounting hole 17 is provided in the non-displayregion 16 of the touch panel 10.

In some embodiments, the mounting hole 17 is defined in the middle ofthe bottom region of the touch panel 10, so that the touch panel 10presents an approximately symmetrical structure. Thus, the terminal 1000has a better appearance and is easy to be operated by the user.

When the mounting hole 17 is configured as the through hole, duringmanufacture of the input assembly 100, the decoration enclosure 20 canbe mounted into the mounting hole 17 from underneath of the touch panel10 firstly, and then an adhesive is dispensed in a gap between an innerwall of the mounting hole 17 and the decoration enclosure 20, so thatthe decoration enclosure 20 is fixedly coupled to the touch panel 10.

Subsequently, the fingerprint chip package structure 30 is mounted intothe decoration enclosure 20 from above of the touch panel 10, and thefingerprint chip package structure 30 is fixedly coupled to thedecoration enclosure 20 through the adhesive.

When the mounting hole 17 is configured as the blind hole, thefingerprint chip package structure 30 can be mounted into the decorationenclosure 20 firstly, then the decoration enclosure 20 carried with thefingerprint chip package structure 30 can be mounted into the mountinghole 17, and the adhesive can be used to adhere and fix the decorationenclosure 20 to the touch panel 10.

Referring to FIGS. 3-5, in some embodiments, the decoration enclosure 20includes a decoration ring 21 and a support rim 22. The support rim 22is configured to support the fingerprint chip. The support rim 22extends inwards from an inner wall 211 of the decoration ring 21.

The support rim 22 of the decoration enclosure 20 according toembodiments of the present disclosure can support and position thefingerprint chip package structure 30, thereby improving an assemblingefficiency of the fingerprint chip package structure 30 and thedecoration enclosure 20.

That is to say, the fingerprint chip package structure 30 is supportedon the support rim 22. When the fingerprint chip package structure 30 ismounted into the decoration ring 21, the fingerprint chip packagestructure 30 can be pressed from top to down. If the fingerprint chippackage structure 30 cannot be moved any more, it indicates that thefingerprint chip package structure 30 abuts against the support rim 22and is mounted to a preset location.

In some embodiments, the decoration ring 21 defines an accommodatinghole 212, and the support rim 22 is located in the accommodating hole212. The accommodating hole 212 can be configured to have a straightcylinder shape, or that is to say, the inner wall 211 is configured tobe straight, so that the fingerprint chip package structure 30 is easyto be mounted in the accommodating hole 212 rapidly.

The accommodating hole 212 and the support rim 22 can be formed byremoving materials from the parts through cutting process, or can beformed by casting.

For ensuring the strength of the decoration enclosure 20, in someembodiments, materials of the decoration enclosure 20 can be metal, forexample stainless steel materials, thereby satisfying strengthrequirements of the decoration enclosure 20 as well as providing acorrosion resistance and improving a service life of the decorationenclosure 20. Certainly, the decoration enclosure 20 can also be made ofother materials, such as plastics.

In some embodiments, furthermore, the fingerprint chip package structure30 is accommodated in the decoration ring 21 and supported on thesupport rim 22.

In some embodiments, the support rim 22 is perpendicular to the innerwall 211 of the decoration ring 21.

Thus, the support rim 22 is easy to be formed, thereby reducing aproduction cost of the decoration ring 21. In addition, when the inputassembly 100 is manufactured, the support rim 22 is located in ahorizontal position, and the inner wall 211 of the decoration ring 21 islocated in a vertical position, so that a surface of the fingerprintchip package structure 30 fitted with the support rim 22 is a horizontalsurface, thereby simplifying a structure of the fingerprint chip packagestructure 30 supported on the support rim 22.

In some embodiments, the decoration ring 21 includes a first bottomsurface 213 connected to the inner wall 211, and a lower surface 221 ofthe support rim 22 is flush with the first bottom surface 213.

Among the decoration rings 21 having a same height, the decoration ring21 having an arrangement described above has a relatively largeaccommodating space, so as to ensure that the fingerprint chip packagestructure 30 can be accommodated in the decoration ring 21.

Or, that is to say, in the case that the fingerprint chip packagestructure 30 has a constant thickness, a height of the decoration ring21 is relatively small, thus reducing a height of the input assembly100, thereby providing a design basis for reducing a thickness of theterminal 1000.

In some embodiments, the decoration ring 21 includes a top wall 214. Thetop wall 214 is connected to the inner wall 211. The top wall 214includes a guiding surface 2142 facing towards an interior of thedecoration enclosure 20.

In this way, the guiding surface 2142 can guide a finger of the user toenter the decoration ring 21 smoothly, so as to perform fingerprintidentification operations, thereby improving an accuracy of the userperforming the fingerprint identification operations. Furthermore, theguiding surface 2142 can be coated with a shiny metal layer (such as achromium layer), so that the decoration ring 21 has a better appearance.

In some embodiments, the guiding surface 2142 can be configured as anannular surface, thereby facilitating the user to place the fingerthereof in the decoration ring 21 from respective directions, so as topress the fingerprint chip package structure 30 and perform thefingerprint identification operations.

In some embodiments, the support rim 22 has a hole 222 therein.

Thus, the hole 222 contributes to a routing layout of a flexiblefingerprint circuit board 40 coupled to the fingerprint chip packagestructure 30. For example, the flexible fingerprint circuit board 40 canrun through the hole 222 so as to be coupled to the fingerprint chippackage structure 30 (as shown in FIG. 2). The flexible fingerprintcircuit board 40 is configured to transmit a fingerprint signal betweenthe fingerprint chip package structure 30 and a mainboard of theterminal 1000.

In some embodiments, the hole 222 is configured to have a roundedrectangle shape. A side wall 2221 surrounding the hole 222 has a groove2222 along an axial direction (i.e. a left-right direction shown inFIG. 1) of the hole 222, and the groove 2222 is communicated with thehole 222.

For example, as shown in FIG. 2, after being coupled to the fingerprintchip package structure 30, the flexible fingerprint circuit board 40firstly extends in a direction towards the groove 2222, then is bent andextends in an opposite direction running away from the groove 2222.Therefore, the groove 2222 can prevent the flexible fingerprint circuitboard 40 from producing an interference with the side wall 2221, therebyfacilitating wiring of the flexible fingerprint circuit board 40.

In some embodiments, the decoration enclosure 20 includes a flange 23extending outwards from an outer wall 215 of the decoration ring 21.

Thus, the flange 23 can abut against the lower surface 14 of the touchpanel 10, thereby increasing a connecting area between the decorationenclosure 20 and the touch panel 10, and improving the reliability offixedly connecting the decoration enclosure 20 with the touch panel 10.

In addition, when the decoration enclosure 20 is mounted into themounting hole 17 from bottom to top, if the flange 23 abuts against thelower surface 14 of the touch panel 10, it indicates that the decorationenclosure 20 is mounted to a preset position. Therefore, the flange 23is provided to improve the assembling efficiency of the input assembly100 and to reduce the production cost of the input assembly 100.

In some embodiments, a sealing sheet can be provided between the flange23 and the lower surface 14, so as to prevent water from entering theterminal 1000 through a gap between the decoration enclosure 20 and themounting hole 17, thereby improving a water resistance effect of theterminal 1000.

In embodiments shown in FIGS. 3-5, the flange 23 and the decoration ring21 are integrally formed. However, in embodiments shown in FIG. 6 andFIG. 7, the flange 23 and the decoration ring 21 are separately formed.In some embodiments of the present disclosure, the decoration ring 21includes a muff-coupling portion 24, and the muff-coupling portion 24 isconnected to the support rim 22. The flange 23 is fitted over themuff-coupling portion 24. Since the flange 23 and the decoration ring 21are separately formed, production difficulties of the decorationenclosure 20 can be reduced, so that uniformity of each decorationenclosure 20 can be improved when the decoration enclosure 20 is putinto mass production.

In some embodiments, the muff-coupling portion 24 can have a throughhole 24 a through which the flexible fingerprint circuit board 40 canrun.

In some embodiments of the present disclosure, the muff-coupling portion24 includes a connecting rim 241 and a bearing plate 242. The connectingrim 241 is connected to the support rim 22 and the bearing plate 242.The connecting rim 241 is substantially perpendicular to the support rim22. The bearing plate 242 is substantially perpendicular to theconnecting rim 241. The connecting rim 241 has the through hole 24 atherein.

The muff-coupling portion 24 is hollow so as to accommodate a part or awhole of the fingerprint chip package structure 30. In some embodiments,the fingerprint chip package structure 30 can be supported on thebearing plate 242.

Referring to FIGS. 3-5 again, in some embodiments, the flange 23 isperpendicular to the outer wall 215 of the decoration ring 21.

Thus, the manufacturing process of the decoration enclosure 20 is easy,and a contact area of the decoration enclosure 20 and the touch panel 10can also be improved, in which the contact area is used for connectionbetween the decoration enclosure 20 and the touch panel 10.

In some embodiments, the flange 23 includes a first protrusion 231 and asecond protrusion 232 coupled to the first protrusion 231. The firstprotrusion 231 includes a first portion 2311 and a second portion 2312.The second portion 2312 is coupled to the first portion 2311 and thesecond protrusion 232. The second portion 2312 protrudes beyond thefirst portion 2311 and the second protrusion 232, that is, an outer edgeof the second portion 2312 has a larger distance from the outer wall 215of the decoration ring 21 than outer edges of the first portion 2311 andthe second protrusion 232.

After the decoration enclosure 20 is mounted in the mounting hole 17,the first portion 2311 and the second protrusion 232 extend along atraverse direction of the touch panel 10 and the second portion 2312extends along a longitudinal direction of the touch panel 10.

As the non-display region 16 has a relatively large arrangement space inthe traverse direction, the second portion 2312 can protrude beyond thefirst portion 2311 and the second protrusion 232, so as to increase aconnecting area of the flange 23 and the touch panel 10.

In addition, widths of the first portion 2311 and the second protrusion232 are relatively small, thereby avoiding a longitudinal size of thenon-display region 16 of the touch panel 10 from being increased due tothe widths of the first portion 2311 and the second protrusion 232, suchthat an area ratio of the display region 15 to the touch panel 10 willnot be reduced, and thus the appearance of the terminal 1000 will not beaffected.

In some embodiments, a top surface 231 a of the first protrusion 231 isflush with a top surface 232 a of the second protrusion 232, and athickness of the first portion 2311 is larger than a thickness of thesecond protrusion 232.

In some embodiments, when the decoration enclosure 20 is mounted in themounting hole 17, the second protrusion 232 is closer to the displayregion 15, compared to the first portion 2311. Or, that is to say, thefirst portion 2311 is away from the display region 15, and the secondprotrusion 232 is close to the display region 15.

As there are more parts in a portion of the input assembly 100 close tothe display region 15, the second protrusion 232 will not have aninterference with other parts close to the display region 15 due to thesmall thickness of the second protrusion 232 (as shown in FIG. 2).

As shown in FIG. 2, an orthographic projection of the decorationenclosure 20 in the lower surface 14 of the touch panel 10 overlapsorthographic projections of the flexible screen circuit board 50 coupledto the screen 80 of the terminal 1000 and of other parts in the lowersurface 14 of the touch panel 10, as indicated by a region limitedbetween two dotted lines in FIG. 2, while the second protrusion 232 willnot have an interference with the flexible screen circuit board 50 andthe other parts due to the small thickness of the second protrusion 232,so that the decoration enclosure 20 can be closer to the display region15 and even can be partially or entirely in the display region 15 of thetouch panel 10, thus reducing an area ratio of the non-display region 16to the touch panel 10 and improving the area ratio of the display region15 to the touch panel 10. The flexible screen circuit board 50 isconfigured to transmit a display signal between the screen and themainboard of the terminal 1000.

In some embodiments, the orthographic projection of the decorationenclosure 20 in the lower surface 14 of the touch panel 10 maycompletely overlap the orthographic projection of the flexible screencircuit board 50 in the lower surface 14 of the touch panel 10, but thepresent disclosure is not limited to this. For example, in otherembodiments, the orthographic projection of the decoration enclosure 20in the lower surface 14 of the touch panel 10 may partially overlap theorthographic projection of the flexible screen circuit board 50 in thelower surface 14 of the touch panel 10.

In some embodiments, the decoration ring 21 is configured to have a longcircle shape. The outer wall 215 of the decoration ring 21 includes twostraight segments 2151 in parallel and two curved segments 2152 eachcoupled to the two straight segments 2151. The first portion 2311 isprovided to one of the two straight segments 2151, and the secondportion 2312 is provided to each curved segment 2152. As shown in FIG.5, two second portions 2312 are provided, and the two second portions2312 are provided to the two curved segments 2152 respectively.

Thus, the decoration ring 21 has the better appearance. In someembodiments of the present disclosure, the two curved segments 2152 arearrayed in two lines along the traverse direction (for example theleft-right direction shown in FIG. 1) of the touch panel 10, and the twostraight segments 2151 are arrayed in two lines along the longitudinaldirection (perpendicular to the traverse direction) of the touch panel10.

In some embodiments, a shape of the second portion 2312 is matched witha shape of the curved segment 2152.

For example, an outer contour of the second portion 2312 also has an arcshape, and the second portion 2312 and the curved segment 2152 aresubstantially concentrically arranged, so that the decoration enclosure20 has a more compact structure.

Referring to FIG. 8-FIG. 10, in some embodiments, the fingerprint chippackage structure 30 includes a package body 31 and a fingerprintidentification chip 32.

The package body 31 includes a second bottom surface 311 and a lateralsurface 312 connected to the second bottom surface 311, and a recessedportion 33 is formed at a junction of the second bottom surface 311 andthe lateral surface 312. The fingerprint identification chip 32 isreceived in the package body 31.

In the fingerprint chip package structure 30 according to embodiments ofthe present disclosure, the recessed portion 33 can be fitted with thesupport rim 22 of the decoration enclosure 20, thereby positioning thefingerprint chip package structure 30, and further improving theassembling efficiency of the fingerprint chip package structure 30.

In addition, since the recessed portion 33 is fitted with the supportrim 22, a thickness of the fingerprint chip package structure 30 can bereduced, thus facilitating miniaturization of the terminal 1000 to whichthe fingerprint chip package structure 30 is applied.

In some embodiments, when the user performs an operation to unlock theterminal 1000 via a fingerprint, the finger can be put in a positioncorresponding to the fingerprint identification chip 32. A signal of thefingerprint identification chip 32 is transmitted through the packagebody 31 so as to collect and identify a fingerprint pattern of the user,and then the fingerprint pattern of the user is matched with a prestoredfingerprint pattern. If the matching is successful, the terminal 1000 isunlocked.

In some embodiments, a surface of the fingerprint identification chip 32facing towards the finger of the user is provided with a sensing pixelarray, so as to collect the fingerprint pattern of the user. The packagebody 31 packages the fingerprint identification chip 32, so as to reduceinfluences of other interference signals on the sensing pixel array whenthe sensing pixel array collects the fingerprint pattern, thus improvingan accuracy of the identification.

In some embodiments, the recessed portion 33 is configured to be fittedwith the support rim 22, that is to say, the support rim 22 isconfigured to be accommodated in the recessed portion 33, so that thefingerprint chip package structure 30 is supported on the support rim 22through the recessed portion 33.

In the present embodiment, the recessed portion 33 is configured to beannular. Correspondingly, the support rim 22 also is configured to beannular, so that the recessed portion 33 can accommodate the support rim22.

In other embodiments, a plurality of recessed portions 33 spaced apartfrom one another along a circumferential direction of the junction ofthe second bottom surface 311 and the lateral surface 312 can beprovided, and correspondingly, a plurality of support rims 22 spacedapart from one another along the circumferential direction can be alsoprovided. The plurality of recessed portions 33 are fitted with theplurality of support rims 22 correspondingly.

For example, three recessed portions 33 can be provided, and twoadjacent recessed portions 33 are spaced apart from each other by 120°along the circumferential direction. Three support rims 22 can also beprovided, and the three support rims 22 are corresponding to the threerecessed portions 33 with respect to the structural position.

In some embodiments, the shape and the number of the recessed portion 33are not limited to the above-discussed cases, as long as the recessedportion 33 is fitted with the support rim 22, so that the support rim 22can support the fingerprint chip package structure 30. Therefore, theabove-mentioned examples cannot be construed to limit the presentdisclosure.

Certainly, in some embodiments, when the thickness of the fingerprintchip package structure 30 is relatively small, the recessed portion 33can be omitted from the fingerprint chip package structure 30.

In some embodiments, the package body 31 includes a first packageportion 313 and a second package portion 314 coupled to the firstpackage portion 313. The first package portion 313 includes the secondbottom surface 311, and the second package portion 314 includes thelateral surface 312.

Thus, the recessed portion 33 can be defined by the first packageportion 313 and the second package portion 314. For example, the packagebody 31 can be provided with the recessed portion 33 by cutting offmaterials from the package body 31, i.e. via the cutting process, or therecessed portion 33 can also be directly formed together with thepackage body 31 by casting.

In some embodiments, for forming the recessed portion 33, across-section area of the first package portion 313 is smaller than across-section area of the second package portion 314.

In some embodiments, the first package portion 313 is received in thehole 222, and the second package portion 314 is supported on the supportrim 22.

In some embodiments, the fingerprint identification chip 32 is receivedin the first package portion 313.

Thus, a circuit junction of the fingerprint identification chip 32 iseasy to be exposed, so as to be coupled to the flexible fingerprintcircuit board 40.

In some embodiments, a shape and a size of the first package portion 313are matched with a shape and a size of the fingerprint identificationchip 32.

Or, that is to say, the shape of the fingerprint identification chip 32is similar to or same with the shape of the first package portion 313.For example, the fingerprint identification chip 32 is configured tohave a cuboid shape and the first package portion 313 is configured tohave a cuboid or a rounded cuboid shape.

The size of the first package portion 313 is slightly larger than thesize of the fingerprint identification chip 32, so as to achieve aneffect of packaging the fingerprint identification chip 32. Thus, thefingerprint chip package structure 30 has the more compact structure.

In some embodiments, the first package portion 313 has the roundedcuboid shape.

Thus, the package body 31 can be better fitted with the fingerprintidentification chip 32. Furthermore, the shape of the first packageportion 313 is matched with a shape of the hole 222, that is to say, thehole 222 also has the rounded cuboid shape.

In some embodiments, the second package portion 314 includes a topsurface 3141 connected to the lateral surface 312. The fingerprint chippackage structure 30 includes a cover plate 34 fixed on the top surface3141 of the second package portion 314. For example, the cover plate 34can be fixed on the top surface 3141 of the second package portion 314through adhesive.

When the user performs the fingerprint identification operation, thefinger can press on the cover plate 34. The cover plate 34 can protectthe package body 31 from being damaged, so as to improve the reliabilityof the fingerprint chip package structure 30.

As the cover plate 34 suffers touches frequently, the cover plate 34 canbe made of materials having high hardness, for example the sapphiresmaterials mentioned above.

In some embodiments, a shape and a size of the cover plate 34 arematched with a shape and a size of the top surface 3141 of the secondpackage portion 314.

For example, the top surface 3141 is configured to have a long circleshape, and the cover plate 34 is also configured to have a long circleshape. An area of the cover plate 34 is slightly larger than an area ofthe top surface 3141 of the second package portion 314. Thus, the coverplate 34 can cover the second package portion 314 entirely.

In some embodiments, a sealing member 60 is provided between the secondpackage portion 314 and the support rim 22. The sealing member 60 isconfigured to seal a gap between the second package portion 314 and thesupport rim 22. For example, the sealing member 60 is made of silica gel(as shown in FIG. 2).

Thus, the sealing member 60 can prevent foreign matters (such as waterand dust) from entering the terminal 1000 from a gap between thefingerprint chip package structure 30 and the decoration enclosure 20,thereby improving the waterproof and dustproof effects of the terminal1000.

In some embodiments, the recessed portion 33 includes a first surface331 and a second surface 332 connected to the first surface 331, and thefirst surface 331 is perpendicular to the second surface 332.

Thus, the recessed portion 33 is easy to be formed, and the firstsurface 331 is easy to be connected to the support rim 22. The firstsurface 331 is perpendicular to the second surface 332, so that thepackage body 31 is configured to have a stepped shape.

In some embodiments, the sealing member 60 is between the first surface331 and the support rim 22.

In some embodiments, a junction of the first surface 331 and the secondsurface 332 is configured to be a transition fillet.

Thus, defects (such as cracks) are not easy to occur at the junction ofthe first surface 331 and the second surface 332 and the recessedportion 33 is easy to be formed.
